Understanding Magnesium Deficiency: Symptoms, Causes and Treatments


Magnesium is an essential mineral that plays a vital role in many of our bodily functions, including the regulation of our heart rate, blood pressure, and blood sugar levels. However, magnesium deficiency is a common problem, affecting up to 80% of the population in some countries. In this article, we’ll explore the symptoms, causes and treatments for magnesium deficiency, and why it’s so important to get enough of this vital mineral.


Symptoms of Magnesium Deficiency

The symptoms of magnesium deficiency can be subtle and often mimic other health conditions. Some of the most common symptoms include:

  • Fatigue and weakness
  • Muscle cramps and spasms
  • Loss of appetite
  • Nausea and vomiting
  • Abnormal heart rhythms
  • Insomnia
  • Anxiety and depression

It’s important to note that these symptoms can be caused by a number of different health conditions, so if you’re experiencing any of these symptoms it’s best to speak to your doctor.

Causes of Magnesium Deficiency


There are several reasons why you might not be getting enough magnesium, including:

  • Poor dietary intake: A diet that is low in magnesium-rich foods, such as leafy greens, nuts, and seeds, can contribute to magnesium deficiency.
  • Chronic alcoholism: Alcohol can interfere with the absorption of magnesium, leading to a deficiency.
  • Chronic diarrhea: This can cause rapid loss of magnesium from the body.
  • Kidney disease: The kidneys play a key role in regulating magnesium levels in the body, so kidney disease can lead to a deficiency.
  • Certain medications: Some medications, such as proton pump inhibitors and diuretics, can interfere with the absorption of magnesium.

Treatments for Magnesium Deficiency

The treatment for magnesium deficiency depends on the underlying cause of the deficiency. In many cases, increasing your dietary intake of magnesium-rich foods and supplements can help to improve your magnesium levels.

If your magnesium deficiency is caused by a health condition, such as kidney disease or chronic alcoholism, your doctor may recommend treatment for that condition to help improve your magnesium levels.

In severe cases, your doctor may prescribe intravenous magnesium therapy, which involves delivering magnesium directly into your bloodstream through an IV.

Why Magnesium is so Important


Magnesium is an essential mineral that is involved in over 300 different chemical reactions in the body. Some of the key functions of magnesium include:

  • Regulating heart rate and blood pressure
  • Supporting healthy bones
  • Maintaining normal nerve and muscle function
  • Regulating blood sugar levels
  • Supporting a healthy immune system

Getting enough magnesium is crucial for maintaining good health, so it’s important to make sure you’re getting enough of this essential mineral in your diet.


Magnesium deficiency is a common problem that can have a significant impact on our health. Understanding the symptoms, causes, and treatments of magnesium deficiency is essential in order to maintain good health and prevent the development of more serious health conditions. If you’re concerned about your magnesium levels, speak to your doctor to get a proper diagnosis and treatment plan.
